Inverted Earth

Abstract

The inverted spectrum argument challenges the computational approach to the mind with the possibility that things we both call red look to you the way things we both call green look to me even though we have the same computational makeup. This paper presents a different argument to the same conclusion based on the example of inverted earth, a place where colors and color language are both “inverted”. It is argued that the inverted earth argument is superior to the inverted spectrum argument.
